Yeah, but think about actually using a rock that thin as a knife. We’re not talking galvanized steel here. You could use it for what, one cut? And hope that works before it breaks into pieces?
Obsidian scalpels are used in medicine successfully, they’re ridiculously sharp. I’m not a rockalogist to say it would or wouldn’t have been useful tho

They’re also very delicate. Not to say obsidian isn’t/wasn’t used for cutting tools, but afaik they were thicker and just knapped on the edge.
